Definitions
- an MBMS service area is defined as a range in which MBMS sessions are conducted.
- the service area is set up in a regional unit such as the whole of Japan, the Kanto area, and the like, and the service area is constituted of a plurality of cells therein.
- delivery paths of multicast data (which will be called multicast delivery paths hereinbelow) are configured in the interior of the EPC (Evolved Packet Core) that constitutes the EPS and the interior of a radio access network such as E-UTRAN, UTRAN or the like that is connected to the EPC.
- EPC Evolved Packet Core
- This conventional multicast data delivery is implemented not by cell units but by service area (the MBMS service area defined in non-patent document 1) units. Accordingly, if there are a cell in which no terminal to be serviced exists inside the service area, the data is distributed to the base station of the cell with the start of delivery the multicast data.
- the receiver terminals are distributed over a geographically wide range, so that the probability of cells in which no terminal exists among all the cells constituting the service area becomes relatively low. As a result, data distribution to the base stations of such cells has not caused a serious problem.
- it is expected in the future that multicast services aimed at only a narrow area increases as a new mode of multicast service.
- multicast services not only to aim at human as user but also aim at objects (machines) (e.g., information distribution for maintenances of machines such in a factory etc., and vending machines etc. densely disposed in a commercial facility, information distribution for public information display such as in a town, in the train, etc.,) may also be considered.
- machines e.g., information distribution for maintenances of machines such in a factory etc., and vending machines etc. densely disposed in a commercial facility, information distribution for public information display such as in a town, in the train, etc.
- a mobility management apparatus of the present invention is a mobility management apparatus formanagingmobile station apparatuses, connected to a mobile communication system in which a service area is constituted of a plurality of cells each disposing a base station apparatus, and which offers a multicast service to a mobile station apparatus existing in the service area, by transmitting multicast data from a multicast service delivering apparatus to the base station apparatuses in the service area, and comprises:
- the mobility management apparatus of the present invention further comprises:
- Service announcement functional unit 150 is a functional unit for announcing information on services (start time, end time, explanation on content, etc.) to UEs 50 of users.
- information on UE 50a is configured so that UE 50a has an identifier of "IMSI-1" and exists in a cell identified as "Cell ID-1".
- information on UE 50b (IMSI-2) having attached or location registered is configured so that it exists in the same cell "Cell ID-1" as UE 50a.
- Information on UE 50c (IMSI-3) is configured so that it exists in a cell "Cell ID-2”.
- This location management information 344 stored based on the result of attachment or location registration is information that is constantly updated when UEs 50 exist in cells, not limited to the case where multicast is implemented.
- the capability of a mobile station may be considered in various ways. Although not shown in FIG. 4 , the capability is the abilities relating to mobile communication, including for example, the types of connectable radio interface, the types of connectable networks (connectable to circuit switched networks alone, packet switched networks alone, or to both), the class of required QoS (quality of service) and others.
- SAI is an identifier that indicates the conventional fixed service area and is included to identify eNBs 40 included in the MBMS service area in the radio access network level. Additionally, inclusion of a dynamic service area constitution identifier other than this, to a message makes it possible for MME 30 to determine that a dynamic service area should be constituted.
- the content of the message field in the service area identifier is given with SAI-n.
- UE capability is managed in UE management information 346, by referring to location management information 344.
- Step S10 when UE 50's participation in a multicast group is set up (Step S10), UE management information 346 that relates the identifier IMSI of UE 50, the identifier Cell IDs of the cell in which the UE exists and its surrounding cells and the identifier TMGI of the multicast group is stored in (Step S12).
- Step S12 if there is another UE 50 that requests for participation in the multicast group, Step S12 is implemented in the same manner.
- Step S16 when no dynamic service area constitution identifier is included at Step S16 and it is hence determined that no dynamic service area will be constituted, all the eNBs 40 that constitute the MBMS service area under the umbrella of MME 30 participate in the delivery paths in accordance with the MBMS service area that has been statically defined in advance.
- a default bearer is set up between UE 50 and S-GW (Serving GW), and MME 30 stores the bearer ID of the default bearer.
- the bearer ID is an ID that is unique to each UE 50 for which a default bearer is set up, and MME 30 can identify the address of the UE 50 defining the end of the bearer.
- the S-GW is a node that is disposed in the core network and is set up as the default router for UE 50. Though this S-GW is not illustrated on the system configuration in FIG. 1 since it may be functionally integrated with MBMS-GW 20, herein the S-GW and MBMS-GW 20 are intentionally shown separately in order to make the operation of the S-GW as the default router and the operation of MBMS-GW 20 distinct from one another.
- the Cell ID which MME 30 manages in UE management information 346 based on location management information 344 is the identifier of the cell to which UE 50 has attached or location registered most recently, but MME 30 may have an additional step of updating the Cell ID by inquiring of the eNB of the cell whether UE 50 exists or not within the cell (S110). Upon updating, the Cell IDs of the surrounding cells can also be updated from eNB information 342 based on the Cell ID of the cell in which UE exists.
- MME 30 may either make an inquiry to eNB 40 of the concerned cell alone, or may make inquiries to all the eNBs of the cells located in the range of the tracking area which MME 30 manages in order to perform paging to UE 50, not limited for multicast services.
- MME 30 identifies the cells for UE 50, based on TMGI
- UE management information 346 stored by MME 30 of the present embodiment is information that associates TMGI, IMSI and Cell ID.
- MME 30 identifies the Cell IDs by referring to UE management information 346 based on this IMSI at S120.
- FIG. 14 is a diagram for illustrating the system configuration of the third embodiment of the present invention.
- MCE 35 is configured independently from eNBs 40 (eNB 40a, eNB 40b, eNB 40c) of the second embodiment. This configuration enables MCE 35 to function as a superior node of eNBs 40 and perform efficient coordination of radio resources.
- eNBs 40 upon selection of eNBs 40, by selecting eNB 40 for the cell in which UE exists and multiple eNBs 40 for the surrounding cells adjacent to the cell in which the UE exists despite the fact that the cell in which UE 50 exists is a single cell, it is possible to make full use of the function of MBMS multi-cell transmission mode (the function of UE 50 located at the edge of cell to improve the quality of reception by synthesizing data received from a plurality of eNBs 40) and it is also possible to easily deal with the movement of UE 50 to an adjacent cell.
- the function of MBMS multi-cell transmission mode the function of UE 50 located at the edge of cell to improve the quality of reception by synthesizing data received from a plurality of eNBs 40
- the program to be operated in each apparatus in each of the embodiments is a program (program that makes a computer function) for controlling a CPU or the like so as to realize the functions of the above-described embodiment modes.
- the information to be handed in these apparatus is temporarily stored in a temporary storage device (e.g., RAM) at the time of processing, then is stored into various storage devices such as ROM and/or HDD and is read out, modified and written in by the CPU, as necessary.
- a multicast session has been once established based on the MBMS service area, but if it is determined that setup of delivery paths in the whole area is no longer necessary because of leaving of UE 50 from the cell or the like, it is easy to decide on constituting a dynamic service area so that switching from the MBMS service area to the dynamic service area can be done.
- a decision may be made so as to switch from the MBMS service area to the dynamic service area.
- the value of X can be designated by, for example, the mobile operator or by a content provider.
- uni-cast transmission (data is transmitted individually to each of UEs 50 which exists serving area) may be used only for the radio bearer between UE 50 and eNB 40.
- a UE identifier for example, in a case of a cell configuration shown in FIG. 17(b) where UE 50a exists in cell 1 and UE 50b and UE 50c exist in cell 2, a UE identifier, Cell ID of the cell in which UE exists, and Cell IDs of surrounding cells are related and stored.
